It's working fine.
suddenly one of my plugin "Better WP Security" is peaking some 404 error that occurred due to the redirection is NOT WORKING, like:
/2012/02/22/off-track-bandorban-2012. Using the "Omnisearch" from "JetPack" I search with the 404 URI reported by the plugin, and find the link inside the post, and then just edit it to
/off-track-bandorban-2012, and it works. After then the 404 doesn't log.
I'm also using a plugin named "Redirection". When I did the .htaccess tweak, I found an entry exactly translating toscho's solution, saying that it'll redirect the archive-linked-posts to simple-posts. And now it's still showing so, but I think the redirection is not working.
